How to enhance video quality?

Forensic video enhancement is the process of clarifying the events using non-destructive techniques, to preserve the integrity of the pixel quality. When we enhance video quality, we enhance the events as they occurred assists the trier of fact to make determinations.

The success of the enhancement hinges on application of enhancement techniques and overall quality of the original video recording (frame rate, video resolution, bit rate).

Video Enhancement Investigation Process

Often times we will perform a preliminary analysis to ensure we  are confident in meeting our client’s expectations. This process requires 1 hour of our lab time in order to apply test enhancements. Once we are confident we can assist, we then enter a full investigation where we create demonstrative video exhibits. These demonstrative video exhibits include motion based highlighting and/or circling, as well as speed reduction.

Each video enhancement investigation is unique, which means no two videos require the same enhancement processes. As a video enhancement company, surveillance video enhancement or CCTV video enhancement is the most common type of investigation we perform. We also enhance law enforcement dash camera videos, smart phone or mobile video recordings and many more. Often times we are asked to provide forensic image enhancement as well for identification purposes.

The most important ingredient to this scientific process is to maintain the highest quality version of the video evidence. This yields the highest success possible throughout the investigation.  The capabilities of the enhancement are  limited if the analog or digital video has undergone additional video compression processes.

Enhance Video Quality Presentation in Court

shutterstock_1047388429-300x200 Forensic Video Enhancement Services, Enhance Video QualityI often provide expert witness testimony services to my clients once a video recording has been forensically clarified. Many courts that I have testified in as an expert witness have video playback equipment. Some of the video equipment that the court provides may not be a high enough quality for higher resolution playback. Other courts like the Federal Court in Boston have more advanced systems where our work product is easier to view.

For example, older systems may not be bright enough for the trier of fact (judge and jury) to preview from. Other arrangements like projects and big screen TV’s can be made if a courtroom doesn’t have more advanced technologies.

Is audio a part of your video evidence? Will the jury be able to hear the audio clearly?  Do you need a PA speaker or amplifier system to make the audio louder for everyone in court to hear? Often times when i am asked to provide testimony, i bring my forensic video enhancement software for presentation to the court. This gives me the ability to play the video quickly with features such as slow motion and frame by frame playback.  We never want to cause a delay in the court proceeding due to technical difficulties.
